J. E. DE COURCY TWISTER Filed Nv. 28, 1928 Patentecl Jan. 21, 1930 UN''ED STATES JOHN E. DE COURCY, OF woncnsrrzs, M'ASSCHUSETTS Applcaton filed. November 28, 1828:

The invention relates to the art of spinning and more particularly t means f0r twisting s1ivers 01 yarns in the formation of threads or cords.

The present invention enables the winding of a greater amount of thread npon a sp001 01 bobbin than is possible by the present cap, ring 01 fiier method, since the bobbin is situated sen1e distance from the twister and is not limited in capacity thereby.

While the drawing illustrates a preferred e1nbodiment of the invention, it is to be understood that in adapting the n1eans to meet speeific needs and requirements, the design 1nay be varied and changes in the minor de tails of construction may be resorted t0 within the sconpe of the invention as c1ai1ned, without departing from the spirit thereoi.

F 01 a fu1l understanding of the invention and the merits thereof, reference is to be had to the following description and the drawing hereunto attached, in which:

Figure 1 is a diagrannnatic view illustrative of the invention in conjunction with a spinning frame.

Figure 2 is a central, longitndinal sectional view of the twister.

Corresponding and like parts are referred to in the foliowing description and designated in bot-h views of the drawing by like reference characters.

Referring t0 Figure 1 of the drawing the nu1neral 1 denotes the back 1011S, 2 the front 1011s and 3 the carrier r011s of a spinning frame. The usual dolly 01 take up r011s are indicated at 4, and 5 designates the bobbin upon which the thread or yarn is wound.

The nmneral 6 designates generally the twister which constitutes the present inventi0n, the same being locatedbetween the delivery 1011s 2 and the take up r011s The twister may be mounted upon the thread board of a spinning frame 01 in any pre- :Eerred or determinate way, according to the design 01 construction of the spinning frame with which it is associated.

The twister comprises a rotatable body and a mount therefor which is ac1apted to be attached to the spinning frame. The body includes a hub 7, a fnnnel 8 and a handle 9.

A passage l0is for1ned in the hub 7 and hand'le 9a11d extends: diagonally from the apexofthe funnei 8 through a si'deof the hand1e9 A second' passage 11 is in coni-municati0n with the passage 10 and extend'sthro1igh be=handle 9at anopposite inclination t0 the passage 10.

The enter end ofthe passage 11 terminates centrally:of thehandle 9; A bleek12-f porcelain 01 analogous mate-rialis set in an opening, .or recess, 0rmed in the end of-the handle. 9 and the passage 11 extends= therethrough. A bleek 13; of porcelain 0r analogou s vitreousmateriai, is set in anopening 01 recess for1ned in the side of: the handle and agroeve: 1'46 f0rnned" in the outer side thereof is in communication with the pas: sages: 10". and 11. The blocks 12 andtl3 resist thnwearof thethread 01" yarn passing there Themennt 01 supporting. fraine i"0= the twister body comprisescomplbmental pistes 183;a11d 19 and a filler 20. These parts When assembled are secnred bymeans of bolts 21:01: 1ike fstening. means; The enter portion. othe hub;7 the ball= bearings 16 and the retainer ringl7are confinedbetween1the p1ates 182111d6 19; The twister 1naybe secnred to the spinning frame= 01 v ether supporting means in any determinate way. The=twister body. may berotated in any mai1nerand is provided with an; annuktr seat or whorl: 22 to receive the usuai .drag band,. not sh0wn,: generally em ployed for rotating the bobbins: or spols of spinning frames; I=nthepreferable constructionz the component parts 01 the twister body are ofintegral formation. 'Il1e passages 10 and 11 are straight and oppositely inclined and open through a side of the handle 9 intermediate the ends thereof.

The sliver or yarn, not shown, is drawn through the passages 10 and 11 by means of a needle 0r slender wire formed into a hook at one end. The slver or yarn passes between the pairs of rolls 1, 2, 3 and 1 and through the iunnel 8 and passages 10 and 11 and is attached to the bobbin or spool 5 to be wound thereon. During the passage of the sliver or yarn through the twister body, some twist is imparted thereto by reason of the corrugated iormation of the funnel and the inclined arrangement 0 the passages 10 and 11. The bobbin 01' spool 5 is located soms distance from the twister, hence is adapted to receive a great amount of thread considerably in excess of that adapted to be wound upon the bobbin by the usual method employing a cap, ring or flier twister. WVhen it becomes necessary to stop a twister to piece up a broken end, or for other cause the handle 9 is grasped. At this time the drag band slides over the whorl 22 in a 1nanner readily understood. Any one of the twisters may thus be tem porarily stopped without throwing th frame out of action as a whole.

The term tunnel as applied to the part 8,

ncludes a bell, or analogous flared part. It is observed that while the passages 10 and 11 are shown straight they may be curved 01 have any preferred form.

Having thus described the invention, I claim 1. A twister comprising a supporting frame, and a twister body rotatably mounted therein and comprising a eentrally disposed hub, a tunnel at one side of the hub and a handle at the opposite side of the hub alined axially wth the funnel, and having oppositely inclined passages formed therein and opening through a side of the handle and through the outer end thereof and in communication with the funnel at the apex thereof, the tunnel being widely fiared whereby the angle of the hub and the tunnel will define a groove to recei"e a driving belt.

2. A twister comprising a supporting frame includng complemental side plates and a bearing held by and between said plates a twister body comprsing a hub fitted between the side plates and journaled in said bearing, a tunnel projecting axially from one side of the hub and widely flared whereby to re- C8VG a driving belt adjacent the side of the hub, a handle projecting axially from the opposite side of the hub and having oppositely inclined passages formed therein leading from the apex of the funnel through a side and the outer end of the handle, and wear-resisting bloeks in said passage at the side of the handle and at the outer end thereof.

In testimony whereof I afiix my signature.
